Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience the pinnacle of sealing technology with our specially designed spiral wound gasket, equipped with a robust solid outer and inner ring. This innovative gasket incorporates an inner ring to elevate performance through enhanced structural integrity. The precision-engineered external guide ring ensures flawless centering on the flange face, providing peace of mind during installation. The inner ring serves a critical role by safeguarding the gasket from extreme temperatures and harsh mediums, filling voids between flanges to prevent erosion, and significantly mitigating failure risks. Crafted from a matching alloy as the winding, the inner ring is essential for gaskets with PTFE filler and is highly recommended for graphite fillers, aligning with the ASME B16.20 and DIN 2699 standards. This adaptable profile excels in both raised and flat-faced flanges. The external ring offers remarkable radial strength, acting decisively as a compression stopper to avert blowouts. Typically constructed from carbon steel with protective coatings to withstand corrosion, it is also available in specialized alloys for demanding high-temperature and severe medium scenarios.
